At the rate they are going with our training sessions and shooting in matches, our best guess they will go through a barrel a season. Though I am not in the business, just providing free barreling work for the kids is enough to keep me busy in the garage at the start of the season.

The skill level of our kids varies from Marksman to High Master. There are but a couple at the HMs, mostly are Sharpshooter and Expert level shooters, we are expecting some to move to Master classification this year.

Having gone through the lengthy intro, I am looking for ideas how to test the AR barrels to determine precision. I read about barrel blocks in some rail guns, don't really know how effective would that be if I were just going to clamp the barrel past the receiver. I could drill a hole through the block for the gas tube. Or would it be better just to install a free float tube and clamp on the tube?

On the platform, my thoughts would just something adjustable bolted to linear bearing. Where I need some suggestion is what material to mount assembly to for a base that is stable enough to minimize warping. Would glued 2 layers of 3/4 MDF suffice? Or steel plate be the preferred material?

Another crossed that my mind is to find a small lathe bed with carriage that I can mount the adjustable platform.

A used return to battery would probably be a good option, I don't think I can sell the going price to the team for funding.

One of the reasons I want to test the barrels so we issue the best barrels to our top shooters who are in contention for winning matches
A lot of matches these days are determined by Xs or 1 or 2 points since CMP and NRA allowed up to 4.5X scopes for service rifles. Right now we just issue barrels and tested in a completed up by the shooter.
As the example an upper was returned to team management as not shooting well enough at 600 yards. We issued the upper to our top junior shooter to shoot at the mid range match. With no zeroes for her on the upper, she lost 2 points initially, but end up with 198-12Xs at 600 in a switching wind.

The SS ratchet barrels we get for free from Shilen shoot, but most likely some may shoot better than others. The high power scoring rings are very generous with 1 MOA X ring, a really good shooting one would mean higher X count at 600, and cleans with high X count at short range, 200 and 300, even considering shooting the rifle on your elbow and sling.

Again, I am looking for opinion on what would be a good system to test AR barrels grouping capability

Thank you all

I know that if it built up from scratch and it has a custom action and yada yada yada, then yeah, definitely want to have it worked on by the same benchrest gunsmith whom built it for you or a benchrest gunsmith at minimum. But is it out of the question to consider taking a factory rifel to a benchrest gunsmith after a regular gunsmith has done everything that can be done on a factory rifle. For example the typical hunting rifle accurized to a target only accuracy level. This would include a New free floating heavy barrel, action bedded, receiver trued, bolt lugs lapped, the typical stuff regular smiths can do. Now you want to drop in new jewell or Canjar trigger, is it at this point that it might be best to start looking for a benchrest gunsmith or is it not going to matter since you still have an accurized factory receiver sleeping in the factory stock which has been modified to suit the upgrades?

Sat, 03 Mar 2018 08:52:59 GMTI've been dinking around testing some barrels from new mfgrs....... for some reason several of them offer only 1.2 shanks VS 1.250.

These skinny shanks don't shoulder up to my liking. They kinda' just 'never really stop' and it scares me......I might try nutting some of them even though it kinda' skews my testing.

I've also got 5-6 testing setups currently set up with barrel nuts. I'm still unconvinced, but testing proceeds apace. I'm testing the barrel nut setups on known-quality blanks (Shilen, Bartlein, Krieger, Lilja) These nuts I've been making from "Grade 8" nuts from the hardware store, because factory options won't take the torque I subject them to. It's a pita.

Is anyone making upgraded, stronger and larger 1 1/16X16tpi 1.350 or 1.250 nuts to sell?

I know that Kiff makes them in standard replacement but I want more strength.....

Mon, 19 Feb 2018 20:03:54 GMTSo for myself, most of my degreasing work is done in mounting scopes and gluing in actions.....degreasing for epoxy work, NOT for rebluing.

I've done the following things before;

-scrub with HOT soapy dish detergent or run thru the dishwasher, scrub with solvent.
-heat with torch and wipe with solvent (NOT recommended in my opinion.... I _think_ the torch leaves greasy residue)
-heat with wife's iron and degrease with solvent.
-heat in wife's oven and degrease with solvent.
-soak in MEK overnite (only solvent I've tried this with)
-scrub in HOT soapy water, heat on a hotplate and scrub (currently with MEK)

Please share thoughts on this.

Sun, 18 Feb 2018 05:28:37 GMTSo, I do a lot of testing stuff...... and, because life is short I try do as many tests at once as I can :)

In this go-round I'm testing 338's set up for 300gr bullets. I'm using 5 platforms to test the 338L, 338RUM, 338 EDGE and "Edge" (3 different throat designs" , 338-378, and my proven variant the 338 McCallum. I rotate them thru a regimen of stocks, AND thru a regiment of tuners.

My project today is a mechanical tension tuning device.

Due to the fact that I'm switching stuff around endlessly I have to bend my rules a bunch. For instance, I typically use one-piece picatinny bases forevermore epoxied onto the actions so they don't (hopefully) move. (I test this by occasionally taking off the scopes, pulling the screws and seeing if it's shot loose.....maybe even firing the rifle with the base screws removed) I've never had an epoxied Stiller shoot loose.

Soooo, I'm fitting a scope to this gun and it needs to be removable so's I can swap barrels....... And I thought, "I know, I'll use cheapo two-piece bases and just screw 'em down! See if they rip right off the gun!" (This pertickler rifle KICKS!!)

THEN I thought......"heck, I'll bolt a scope-checker to the flimsy 6-48 two-piece base setup.... see if THAT will rip it off!"

And THEN I took it one step further........ "I've never done 3 before!"...... this scope checker is set up so's I can bolt either a 1" tube or a 30mm tube.... OR BOTH I guess!
